To all whom it may concern:

Be it known that; I, View J ULInn' MARIE Tnr'isin, a citizen -of the French Republic,- residing at Brest, Department of the F1n1- 6 stere, in France, have invented certain new and useful Improvements" in Sterilizing Sub stances for Toothbrushes and Similar Articles, of which the following is a spec fication.

The invention relates to a sterilizin substance which is adapted to be place in a small box provided in a container of tubular shape and enerally made of glass or crystal. This pplication is a division of my .copending application 640,469 filed May For sterilizing tooth brushes practice has proved that it is very advantageous to shorten as much as possible the-time l1m 1t necessaryl for a complete sterilization, 1n order to allow the use of the brush several times in a day in an effective sterilized state. With this object in view, accordin to the invention, trioxymethylene is genera 1y used, 2 with an addition of ane ual quantity of soda-tungstate, for it has en found that the latter; activates the known properties of the' former. I It acts at the same time as 'an exciter and regulator, practice having demonstrated that the length ofthe operation is reduced ,with said mixture in the ratio or 5 to 1 om ared with the use 0f the trioxymethylene alone. a 1 1 Besides it has been proved that it is ad-l vantageous to add a certain quantity of vegetableessence, such as orange essence or thyme essence, which, on account of the fact that essences possess sterilizing 'ualities, add their action to that of the trloxy- L methylene exhalations. Furthermore, these t"" and of a' essences offer the advantage .of diminishing 'flhe;1 disagreeable smell of the formic aldey e. I

Y The proportions are subject very large variations of 'trioxymethylene, soda-tungstate and vegetable essence (oran e essence,

thyme essence, etc), the latter-inherently teriologists that the time required for effective sterilization is very short, at most four hours, while with formol, for example, 24 hours are necessary and it has to be renewed every three or four days.

,l-Iaving thus fully described the invention what is claimed as new and desired to be secured by Letters Patent is A substance for sterilizing tooth brushes andv like articles comprising a mixture of substaritiallyequal parts of trioiymethylene =and' soda tungstate and a vegetable essence having sterilizing roperquality suflicient to e' ect deodorization.

" A substance as claimed in claim 1, in

wlnch'orange essence is em loyed. j
